The River Valley GCSE CGP(P49) Profiles

The path of a river as it flows downhill is called its ...........

• course

• gradient

• profile

Where is the river course at its steepest?

• the lower course

• the middle course

• the upper course

Which is the flattest part of the course of a river?

• nearest the source

• nearest the mouth

• the lower course

What does the long profile of a river indicate across the course of a river from source to mouth?

• How deep the channels are

• How the gradient changes

• The shape of the valley

What profile shows a cross section of the river from upper course to upper course across the valley

• cross profile

• long profile

• valley profile

The river .......... is the area of a valley through which the water flows.

• bed

• channel

• passage

A long narrow region of low land between ranges of mountains, hills etc. with a river stream or river valley running along its bottom; is a description of what?

• estuary

• flood plain

• valley

In the upper course the long profile is

• often gently sloping valley sides with a wider

  channel

• steep and often an upland area. The river's load is large as it hasn't been broken down by erosion yet

• the land is a lot flatter. The river's load is fine sediment, as erosion has broken down the rocks

The middle course cross profile is

• wider valley floor formed by lateral erosion of meandering river, with gentler valley side -slopes

• narrow and steep-sided due to vertical erosion by the river combined with weathering and mass movement of the valley slopes

• a lot less erosion, with only some lateral erosion with an almost flat valley floor

Rivers (a)   the landscape and transport the material to somewhere further along the course where it is deposited
